Applications

  • Audiometric transducers for hearing threshold testing

  • Bone conduction hearing aids
    - Conventional bone conduction hearing aids
    - Bone anchored hearing aids
    - Implantable hearing aids

  • Communication systems

Conclusions

  • Lower total harmonic distortion (THD) by 20-25 dB

  • Lower counterweight mass by a factor of 3

  • Improved sensitivity by 10 - 20 dB for 100 to 1000 Hzand by 2 - 10 dB for 1 to 10 kHz

  • Improved efficiency as also the electrical inputimpedance is higher by some 1.8 times
